The purpose was to develop and
evaluate a novel approach to MR phase imaging of blood flow and CSF flow by
combining cine phase contrast (cine-PC) with simultaneous multi-slice (SMS)
technique to measure velocity in several slice planes simultaneously. Comparisons
were made between SMS 2-4 and conventional single-slice 2D cine-PC GE imaging.
The velocity curves measured in internal carotid (ICA) and vertebral arteries
and jugular veins and aqueductal CSF were similar between SMS and conventional
single-slice cine-PC. In ICA correlations (R=0.92-0.98) in 6 subjects. This new
ability for simultaneous cross-sectional hemodynamic quantification may be
useful for medical diagnoses.
